React Universe Meetup is coming to Berlin <3
On January 29, 2026, we’re teaming up with Zalando to host an in-person React Universe Meetup at Zalando SE – BHW. Expect an evening built for experienced engineers who care about how things actually work in production, with time for both focused talks and unstructured conversations.
The event is aimed at software developers, senior engineers, and architects working across full-stack and cross-platform applications, with an emphasis on sharing practical lessons, architectural tradeoffs, and production-ready approaches. It’s a space for teams working with React Native and related technologies to compare notes, learn from peers, and take ideas back to their own codebases.
